DISCUSSION
TODAY THROUGH SUNDAY..
A LOW PRESSURE SYSTEM MOVING THROUGH NORTHERN MT IS EXPECTED TO
BRING BREEZY CONDITIONS TODAY AS IT DEPARTS NORTHEAST INTO CANADA.
WEST WIND GUSTS OF 20-30 MPH ARE EXPECTED THROUGH THE DAY AS A
RESULT. AS THE WEEK PROGRESSES INTO TUESDAY, ENERGY MOVING UP
UNDER SOUTHWEST FLOW FROM A LOW SITTING OVER THE PACIFIC NW COAST
WILL MOVE UP FROM WYOMING. THIS IS EXPECTED TO BRING LOW
PRECIPITATION CHANCES TO THE MT/WY BORDER TUESDAY MORNING,
LIFTING NORTH THROUGH THE DAY. ISOLATED TO SCATTERED SHOWERS AND A
FEW THUNDERSTORMS ARE EXPECTED. GIVEN INSTABILITY IS EXPECTED TO
BE MINIMAL, ONLY A FEW WEAK THUNDERSTORMS ARE EXPECTED. ALTHOUGH
THE REGION REMAINS UNDER SOUTHWEST FLOW ALOFT WITH WEAK ENERGY
MOVING THROUGH, THERE ISN'T A REALLY STRONG SIGNAL FOR FORCING.
THERE IS A DECENT SIGNAL FOR A FRONTAL PASSAGE WEDNESDAY WITH SOME
INSTABILITY AROUND, BUT WITH LACK OF EAST WINDS IN THE LOW LEVELS
AND UNCERTAINTY IN FORCING, IT WOULD JUST BE A BREEZY, DRY
FRONTAL PASSAGE. THE REMAINDER OF THE WEEK LOOKS TO BE UNCERTAIN
AS THE REGION REMAINS UNDER SOUTHWEST FLOW, BUT ENSEMBLES SEEM TO
RETREAT ENERGY WEST AS RIDGING OVER THE CENTRAL PLAINS EXPAND
WESTWARD, DIMINISHING THE CHANCE FOR PRECIPITATION.
HIGH TEMPERATURES ARE FORECASTED TO BE IN THE 70S AND LOW 80S
THROUGH TUESDAY, WARMING INTO THE 80S AND LOW 90S THROUGH THE
WEEKEND AS HIGH PRESSURE BUILDS IN FROM THE EAST. TS
AVIATION
EXPECT BREEZY WEST WINDS OVER EASTERN MT TODAY, AROUND 20-30
KTS. VFR WILL PREVAIL. TS
